Japanese filenames

Can someone clue me in as to what order Japanese filenames are displayed in?  That is to say, in English filenames are displayed (ASCII aside) alphabetically, but in what order are Japanese files displayed?  I ask because I'm considering retagging/naming all my Japanese music with the proper kanji/kana titles, but I'm wondering exactly how much of a bitch it will be to find what I want if it's not alphabetical.  I'm guess that maybe the precedence is a, i, u, e, ka, ki, ku, ke, ko and so on?

There's nothing such as "English filenames"; the Unicode international collation algorithm is to be used. For example, with a Spanish local, 'ñ' comes before 'o', even though its Unicode code point is higher. This is at least for non-dinosaur, truly Unicode-compilant OSes i.e. Windows; I doubt it'll work this way under Linux.

Refer to www.unicode.org for the Unicode collation algorithm for Japanese locales, I suppose it must be defined there.
